This breaks DRI3 (uses DMABUF) on drm-next-kmod (Linux 4.9 atm) e.g.,

$ LIBGL_DRI3_ENABLE=1 LIBGL_DEBUG=verbose MESA_DEBUG=context glxgears
libGL: screen 0 does not appear to be DRI3 capable
libGL error: Connection closed during DRI3 initialization failure
XIO:  fatal IO error 35 (Resource temporarily unavailable) on X server ":0"
      after 22 requests (22 known processed) with 0 events remaining.
